Charcoal samples were recovered from the fill from two features at the Paired-Features Site, 41PS735, in west Texas. These charcoal samples were submitted for identification and AMS radiocarbon dating. The site consists of a multi-component open campsite containing a large ring midden, roasting facilities, a possible tipi ring, and scatters of prehistoric and historic artifacts. Recovery of a single corner-notched dart point suggests a Late Archaic component. Charcoal identification determined...

Four charcoal samples from site 10EL1199 in Elmore County, Idaho, were submitted for identification and AMS radiocarbon dating. Ceramic sherds from this site also were submitted for organic residue analysis. Samples were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Organic residue analysis provides information regarding diet, in this case specifically foods processed in ceramic vessels.

Charcoal and charred botanic remains recovered from unit fill at site CA-NEV-1482 in Nevada County, California, were submitted for identification and AMS radiocarbon dating. A steatite bowl fragment from another unit at the site was tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). This site is a Nisenan occupation situated on the shoreline of Lake Combie. Identification of charred botanic remains and charcoal will provide information concerning plant resources...

The T. Thompson site (21CO50), located in Cottonwood County, in southwestern Minnesota, yielded three samples for AMS radiocarbon analysis (Table 1). A ceramic sherd containing visible charred food crust, a bison ulna, and a piece of Ulmus rubra (slippery elm) charcoal were submitted for AMS radiocarbon analysis. Fourier transform infrared spectroscopic (FTIR) analysis also was performed on the charred food crust removed from the ceramic sherd to obtain a signature of the foods cooked.

Site 48SU2242 is a prehistoric open camp situated in the northeastern extent of the Alkali Creek drainage system within the Green River Basin, Sublette County, Wyoming. Several basin-shaped hearths were exposed during the construction of a well pad. Charcoal was collected for identification and AMS radiocarbon dating. Dates for the hearths are expected to range between 2500 and 3200 years BP (Jan Erickson, personal communication December 2, 2014).

A small amount of sediment from a prehistoric burn feature at site 32ME1030, North Dakota, was examined for macrofloral remains and organic residues. Charcoal recovered from the sample was submitted for AMS radiocarbon dating. Organic residues were identified using Fourier Transform Infrared Spectroscopy (FTIR). AMS radiocarbon dates also were obtained for two bison mandible fragments from site 32MZ411. These sites reflect prehistoric campsites found along the shores of Lake Sakakawea in western...

A total of 12 samples from sites 48BH3457 (Alm Shelter), 48BH719, 48WA1938 (Solstice Shelter), 48WA1939 (6 Amigos Shelter), and the Fertig Shelter were submitted for identification and AMS radiocarbon dating. A total of 11 dates were obtained from charcoal. A date also was obtained from uncharred grass matting, originally submitted as a bark sample.

The Dating Iroquoia project is developing high-precision radiocarbon chronologies for northeastern North American archaeology. We are especially concerned with understanding how refined timeframes help us to understand processes of population movement, conflict, settlement aggregation, politogenesis, and the entry and impacts of European manufactured goods and persons among Northern Iroquoian societies.

Mr. Warren Crump provided PaleoResearch Institute access to a painting supposedly depicting Pope Julius II (AD 1443–1513) to determine when the artwork was produced. In addition, PaleoResearch performed an XRF scan of the artwork to identify elements of the pigments used in painting. During the course of radiocarbon age determination, PaleoResearch removed paint and other chemicals present on the linen prior to dating.

A total of eight samples from geologic trenches at the 7 Lagos Project in Valdivia, Chile, were examined to recover organic fragments suitable for radiocarbon dating. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. Two samples appeared to contain charred material in sufficient quantities for dating; however, the charred material did not survive the chemical pre-treatment for dating. Half of the sediment retained during...

A total of six sediment samples were collected at the interface between a distal alluvial fan and playa surface in paleoseismic trenches at Pahrump, Nevada. These samples were examined for the presence of charred organic material suitable for AMS radiocarbon dating. In the absence of larger-sized charred remains, five the samples were extracted to recover microscopic charcoal/particulate soil organics for dating. One of these samples did not yield sufficient particulate soil organics; therefore,...

A total of three bulk soil samples were collected from colluvium in Trench 5 at the Los Angeles Reservoir Ultra Violet Treatment Facility in southern California. These samples were examined for the presence of charred organic material suitable for AMS radiocarbon dating. In the absence of larger-sized charred remains, two of the samples were extracted to recover microscopic charcoal for dating. Two AMS radiocarbon dates were obtained for microscopic charcoal extracted from these sediments.

The Feffer Holloway project site (Holloway BA-4) is located in West Hollywood, southern California. One soil sample, collected with a bucket auger (BA-4) from an alluvial fan deposit, was submitted for macrofloral analysis and subsequent AMS radiocarbon age determination. These deposits are expected to be 30,000 years old.

Eleven bulk soil samples from a paleoseismic trench across the San Andreas Fault at the Filoli site in San Mateo County, California, were floated to recover organic fragments suitable for radiocarbon age determination. These samples were collected from the south and north walls of the trench and range in depth between 0.2–2.5 m below ground surface. Botanic components were identified and potentially radiocarbon datable material was separated. Ten AMS radiocarbon dates were obtained on charcoal...

A total of 21 soil samples from a preliminary fault study on the coastline of northern Mozambique, Africa, were floated to recover organic fragments suitable for radiocarbon dating in hopes that the dates will provide some constraint on the overall age of near surface sediments. The project area is predominantly sand with varying degrees of silt and clay. Botanic components, detrital charcoal, and shell were identified, and potentially radiocarbon datable material was separated. A total of 14...
